Hey guys, I cooked up a mod where I used ASM to change the length of the day-night cycle in the game. While this appears to work quite fine when run from within eclipse, I simply can't get the damn thing packaged to run with my regular forge installation >.< 
  
Specifically, I recompiled, reobfuscated and zipped the files (without the enclosing minecraft folder), then changed the ending to .jar. Also slapped a mcmod.info and a META-INF on it for good measure. The structure inside the .jar is 
daytime.jar 
->daytime 
-->asm 
--->DaytimeLoadingPlugin.class (which implements IFMLLoadingPlugin) 
--->rest of the class files 
->META-INF 
-->MANIFEST.MF 
->mcmod.info 
  
The problem is, when I try to run with this package I get  
  
 
[sEVERE] [ForgeModLoader] Coremod DaytimeLoadingPlugin: Unable to class load the plugin daytime.asm.DaytimeLoadingPlugin
java.lang.ClassNotFoundException: daytime.asm.DaytimeLoadingPlugin
 
  
Google search indicates this usually happens when the folder structure in the package is messed up, but I can't quite see where this would happen.  
Any other ideas what might be amiss here? =/
